Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper
monitor the area behind and next to the vehicle
at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the exterior mirror housing flashes
and the steering wheel vibrates.
Hints Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀

Information stage
The dimmed lamp in the exterior mirror hous‐
ing indicates when there are vehicles in the
blind spot or approaching from behind.
Warning If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the exterior mirror housing
flashes brightly.
The warning stops when the turn signal is
switched off, or the other vehicle leaves the
critical zone.

Driving stability control systemsVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
This system supports driving off on inclines.
The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin to
roll back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.

Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving withroof load
Do not deactivate Dynamic Stability Control
DSC when driving with roof load, e.g. roof-
mounted luggage rack.
Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀

DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC where
forward momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum traction. Driving stability is
limited during acceleration and when driving in
curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.Seite 129Driving stability control systemsControls129
Online Edition for Part no. 01 40 2 954 494 - II/15

xDrive xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
HDC Hill Descent Control
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. walking speed and then keeps its
speed constant.
As long as there is active braking, the system
is on standby. The system does not brake the
vehicle during this time.
Only use HDC in low gears or in selector lever
position D or R.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker switch of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.▷Press the rocker switch up to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point
of resistance: the speed increases while
the rocker switch is pressed.▷Press the rocker switch down to the point
of resistance: the speed decreases gradu‐
ally.▷Press the rocker switch down past the
point of resistance: when driving forward,
the speed decreases to approx.
6 mph/10 km/h; when reversing, the speed
decreases to approx. 4 mph/6 km/h.Seite 130ControlsDriving stability control systems130

▷Dynamic Drive, refer to page 131.▷Dynamic Damping Control, refer to
page 131.
The system increases driving stability and driv‐
ing comfort.
Dynamic Drive
The concept The system reduces the lateral inclination of
the vehicle that occurs during rapid driving in curves or during quick evasive maneuvers.
Driving stability and driving comfort are in‐
creased under all driving conditions. The sys‐
tem utilizes active stabilizer bars on the front
and rear axles that react immediately to all driv‐
ing situations.

Integral Active Steering The concept
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in
a direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.
The rear wheels are turned to the same angle
as the front wheels.
In critical situations, Integral Active Steering
can specifically steer the front and rear wheels
to stabilize the vehicle before the driver inter‐
venes, e.g., when braking where road condi‐
tions differ on the left and right sides of the ve‐
hicle.
InitializingIn rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.1.With the engine running, turn the steering
wheel all the way to the left and right sev‐
eral times in a uniform manner until the
warning lamp disappears.2.Have the system checked if the warning
lamp does not go out after moving the
steering wheel approx. 6 times or if the
steering wheel is at an angle.
Using snow chains
Note When snow chains are in use, refer to
page 205, rear wheel steering is deactivated.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 132.
SPORT
Consistently sporty tuning of the Integral Ac‐
tive Steering for greater driving agility.
Malfunction In the event of a malfunction, the steering
wheel must be turned further, while the vehicle
responds more sensitively to steering wheel
movements in the higher speed range.
The stability-enhancing intervention may be
deactivated.
Proceed cautiously and drive defensively.
Have the system checked.
Driving Dynamics Control
The concept The Driving Dynamics Control can be used to
adjust the driving dynamics of the vehicle. For
this purpose various programs are available for
selection that are activated via the two buttons
of the Driving Dynamics Control and the DSC
OFF-button.
